Rose plant

ABSTRACT

A new miniature rose variety of the light red, deep pink coloring class of good form and substance.

The present invention relates to a new and distinct variety of roseplant of the miniature rose class, which was originated by my crossingas seed parent the rose known as "Operetta" and the rose known as"Bonny" as pollen parent. The varietal denomination of this new varietyis "Pink Triumph".

Among the novel characteristics possessed by this new variety whichdistinguish it from its parents and all other varieties of which I amaware are its well formed, heavily petaled flowers of good exhibitionform and substance which open into symmetrical light red, deep pinkbloom. In the 1/3 to 1/2 open stages flowers combine deeper tonedred-pink coloring where petals bunch with lighter colored outer petals.Asexual reproduction by budding of the new variety as performed in KentCounty, Md., shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations.

The accompanying drawing shows typical specimens of the vegetativegrowth and flowers of the new variety in different stages of developmentand as depicted in color as nearly true as it is reasonably possible tomake the same in a color illustration of this character.

The following is a detailed description of my new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.) The terminology used in color description hereinrefers to plate numbers in the aforementioned color chart, e.g., "52A"is plate 52A of The Royal Horticultural Society Colour Chart.

Parentage: Seedling.

Seed parent.--"Operetta".

Pollen parent.--"Bonny".

Class: Miniature.

The following observations are made of specimens grown outdoors in KentCounty, Md., during the month of August.

1. FLOWER

Blooming habit: Continuous.

A. Bud:

(1) Size.--Medium.

(2) Form.--Long pointed.

(3) Color.--When sepals first divide -- near 52A lightening to 52D.

(4) Sepals.--Longer than bud.

(5) Peduncle.--Length -- 1 to 11/2 inches. Aspect -- Straight. Strength-- Erect. Color -- Near 138A.

B. Bloom:

(1) Size.--Average size when fully expanded -- about 11/2 to 13/4inches.

(2) Borne.--Primarily one to a stem.

(3) Form.--High centered at first, becoming flat, some petals reflex toquills upon opening; others roll under; flower maintains symmetricalexhibition form until center is lost.

(4) Petalage.--Number of petals under normal conditions -- About 46 to50.

(5) Color.--As sepals fall, first color shown appears Carmine rose, near52A, but bud coloring quickly lightens to Spinel red 54C. Somedeeper-toned, 48A to B, appears in veining or washing in petalundersurface and is more pronounced as flowers open. The deeper-tonedcolor is very visible where petals bunch and in 1/3 to 1/2 open stages,the flowers display a combination of Neyron rose, near 55D to 56A,coloring of outer petals and deeper-toned 48A to B flower centers. Thedeeper tonality becomes less visible as flowers open further.

C. Petals:

(1) Texture.--Thick, good substance.

(2) Appearance.--Inside -- velvety, outside -- velvety.

(3) Form.--Rounded, point at apex.

(4) Arrangement.--Regularly arranged, shingle-like.

(5) Petaloids in center.--Medium.

(6) Persistence.--Petals tend to retain.

(7) Fragrance.--Slight.

(8) Lasting quality.--Very long lasting on plant and as cut flower.

2. REPRODUCTIVE ORGANS

A. Stamens, filaments and anthers:

(1) Arrangement.--Regularly arranged around styles.

(2) Color.--Near 16B.

B. Pollen:

Color.--Near 15A.

C. Styles: Uneven, medium length.

D. Stigmas:

Color.--Near 55C.

E. Hips:

Shape.--Globular.

Size.--Medium.

Color.--Orange.

Do seeds protrude? -- No.

3. PLANT

A. Form: Upright, compact.

B. Growth: Very vigorous, uniform branching.

Height attained.--About 24 to 26 inches.

C. Foliage: Compound 5 to 7 leaflets.

(1) Size.--Medium.

(2) Quantity.--Abundant.

(3) Color.--New foliage: Upper side -- Near to 148B tinged with near46A. Under side -- Near to 148C tinged with near 47A. Old foliage: Upperside -- Near 139A. Under side -- Near 191A.

(4) Shape.--Oval, pointed.

(5) Texture.--Upper side is smooth, shiny and under side is matte.

(6) Edge.--Serrated.

(7) Serration.--Serrate.

(8) Leaf stem.--Color -- Near to 138B. Under side -- Near 138B.

(9) Stipules.--Medium, short, pointed.

(10) Resistance to disease.--Blackspot -- Average. Mildew -- Average.

D. Wood:

(1) New wood.--Color -- Near 166A. Bark -- Smooth.

(2) Old wood.--Color -- Near 138A. Bark -- Smooth.

E. Thorns:

(1) Thorns.--Quantity (main stalk): ordinary. On laterals from stalk --Few. Form -- hooked. Length -- Medium. Color -- Near 45D. Position --Irregular.

(2) Prickles.--Few.

F. Winter hardiness: Winter hardy.

I claim:
 1. A new and distinct variety of rose plant of the miniaturerose class, substantially as shown and described, characterizedparticularly by well formed, heavily petalled flowers of light Neyronrose coloring having deeper-toned flower centers where petals remainbunched until opening and with petals reflexing and rolling under uponopening while retaining good form.
